I currently have an Alpine head unit, but it is 3 or 4 years old and now has trouble playing CDRs. I have a small amp & sub, but nothing impressive. Just enough for my little Honda. What I am looking for is a decent head unit that will play CDs, CDRs, and MP3s. I am guessing something around the $300 - $400 range, but not sure, so I turn to the experts of OT. Any recommendations would be appreciated.
